nitrite bacteria
解釋
亞硝酸細菌-
Ammonia - oxidizing bacteria which oxidize ammonia to nitrite is a key group of nitrifying bacteria. the population of ammonia - oxidizing bacteria is variable with the different environment
將氨氧化為亞硝酸鹽的氨氧化細菌是硝化菌群的重要組成部分，它的種類隨生境差異而有所不同。 -
Results showed that in the water body of xizi lake, annual average of culturable planktonic ammonifiers and nitrogen fixers were 510 and 236 cfu / ml, respectively ; ammonia oxidizers, nitrite oxidizers, nitrate reducers and denitrifiers were 8. 5, 16, 587 and 16 mpn / ml, respectively ; inorganic phosphate solubilizing bacteria ( 1pb ) and organic phosphorus mineralizing bacteria ( opb ) were 89 cfu / ml and 37 mpn / ml, aerobic and anaerobic cellulose decomposers were 7 and 5 mpn / ml, respectively
水體中可培養異養細菌（氨化細菌）和固氮菌的年平均值分別為510和236cfu ml ，氨氧化細菌、亞硝酸氧化細菌、硝酸鹽還原菌和脫氮菌的數量分別為8 . 5 、 16 、 587和16mpn ml ；無機磷和有機磷分解菌分別為89cfu ml和37mpn ml ；好氧性纖維素分解菌和厭氧性纖維素分解菌只有7和5mpn ml 。 -
Because there are a great quantity ' s heterotrophic bacteria in the breeding pool, which will have the repulsion action to the insufficient quantity ' s nitrifier and prevent the nitrification, the situation will bring the accumulating of nitrite which is the middle substance of nitrification in water, the long term accumulated nitrite can debase fish and shrimp ' s disease - resistant and decrease the growth and even die
由於養殖池中存在大量的異養菌，受到異養性細菌排斥，本身無足夠數量的硝化菌，硝化作用往往受阻，結果就會引起硝化作用的中間產物亞硝酸鹽在水體內的累積、亞硝酸鹽長期蓄積會使魚蝦等抗病力降低、生長受阻、嚴重者中毒死亡。 -
1. in the mpn - griess method of enumeration of nitrite - oxidizing bacteria, the nitrite concentration deeply effect the enumeration results and detection time. the o. lmmol / l nitrite concentration in the culture is the best choice for mpn - griess method and the shortest detection time is 4 week
硝酸細菌mpn ? griess計數法所用培養基的亞硝酸鹽濃度對計數的周期和結果均有影響，採用0 . 1mmol l亞硝酸鹽的培養基，進行4周的計數培養，是最優的硝酸細菌mpn ? griess計數法。 -
The two methods correlation of ammonia - oxidizers and nitrite - oxidizers are 0. 9593 and 0. 9823, respectively. compared with the conventional mpn method, int dehydrogenase method is more rapid, simpler, and easily operated. the detection periods were shorten from 4 weeks of mpn to 2 days. the int dehydrogenase is a pragmatic method for rapid detection of nitrifying bacteria
採用硝化細菌的偶氮鹽（ int ）還原計數檢測法對活性污泥的硝化細菌進行檢測，所得的結果與傳統的mpn ? griess法檢測值有著很好的相關性， int法檢測周期為2天，具有快速、簡便、操作容易等優點，是一種有推廣價值的硝化細菌快速計數檢測方法。 -
Benjamin ' s group confirmed the antimicrobial effect right away by exposing bacteria responsible for stomach infections to stomach acid both alone and mixed with nitrite
班傑明的研究團隊隨即證實，胃酸本身以及胃酸搭配亞硝酸鹽，對感染胃部的細菌具有抗菌的效果。 -
Benjamin has also observed that cavity - causing bacteria self - destruct in a high - nitrite environment, suggesting an experiment to see if a high - nitrate diet prevents cavities
此外，班傑明還觀察到，造成蛀牙的細菌在高亞硝酸鹽的環境下會自我摧毀，意味著高硝酸鹽飲食或許能做為預防齲齒的新實驗方向。 -
The ammonia - oxidizers were increased from 2. 13 106 / g mlss to 6. 28 108 / g mlss, while the nitrite - oxidizers were increased from 2. 13 103 / g mlss to 6. 28 106 / g mlss. after a month, most of the heteotrophic bacteria were washed out from the system. they nitrifying bacteria were prevalent in the enrichment system and were around 99 % in total bacteria
選取富含硝化細菌的活性污泥作為富集培養的對象，採用純無機培養基對硝化細菌進行定向富集培養，能在較短的時間內得到大量硝化細菌富集培養物，硝化細菌數約占總菌數的99以上。 -
Although acid is often thought to be the stomach ' s main line of defense against invading bugs, the researchers found that e. coli, salmonella and other bacteria could survive for hours in it, whereas high normal concentrations of nitrite plus acid killed the bacteria in less than an hour
雖然我們常視胃酸為胃部抵禦入侵病菌的主要防線，然而研究者卻發現大腸桿菌、沙門氏菌以及其他細菌可以在胃中存活數小時。
